The invention relates to a method and a device for continuously measuring the
moisture content of tobacco. The method is characterized by comprising the following steps: the initial
moisture content of tobacco shreds is determined; the weight of the tobacco shreds is continuously measured under the environment of constant temperature and constant
humidity; measured values are transmitted to a
data analysis module which automatically processes the initial
moisture content and obtained data, so as to form data points of the instant moisture content of a series of tobacco shreds with reference to the time; and a curve of the instant moisture content of the tobacco shreds with reference to the time is made, and the nuance of the moistening effect of tobacco
humectant is compared according to the comparison of the slope coefficient in the earlier stage and the
equilibrium moisture content in the
late stage of the curve. The device comprises a climatic chamber, wherein the climatic chamber is provided with an air inlet and an air outlet; a weighing
machine is arranged inside a chamber body, and is connected with the
data analysis module which is arranged on the outside through a data wire; and the lower part of the chamber body is provided with a
liquid storage tank. By utilization of the method and the device, the weight variation of the tobacco shreds can be monitored online in real time, and the difference of the moistening performance of the tobacco
humectant can be compared by measurement of the nuance of the moisture content of the tobacco shreds, thereby providing scientific reference for evaluation of the moistening effect.
